The spring-suspension means shown consists of aspiral spring disposed, as indicated l in Fig. 1,.its periphery being in close contact x with the walls of the cylinder for spring-seat,

as shown. The inner end orportion is connected to the s oke-connecting rod or shaft v.and may be eit er held in place. by its own- I tension or may be pinned to such rodby any ,1.5 well-knownmeans. 'By havingthe springseats yor cylinders formed of se arate segments, one of which is removab e, an easy 1, 4Ameans is provided for the replacement. of any .i individual spring-should' it become-broken or zo-fforany other reason need to be replaced, as..

`will be seen f As will be readily seen in our construction, each spring has a universal movement, and

` any vweight placed upon ,the wheel will exert ,2 5 a constant and uniform tension on all of said sprin s, noL matter what the position of the whee may be.` In like manner any torque Ior traction force applied to the wheel is transmitted uniformly `to all of said springs, and

3Q they therefore collectively serve the same function, no -matter what position the wheel may be in or the weight or strain u on it. It [will be also seen'thatb v reason o the construction shown all re ative lateral move- 3 5 ment of the-inner and outer wheel portions is prevented, and While the hub moves in the desired plane when the wheel is under tension it has no lateral or disadvantageous movement. ,Y

It is obvious that many modiiications and changes may be made in our invention from the particular embodiment shown, and we do y not limit-ourselves to any specific construction but l What-we claim, and desire to secure by Letters Patent, is-

- 1. A vehicle wheel comprising a hub, a se- .'ries of radiating spokes symmetrically disposed thereon, a rim and a series of inwardly-v 5o` extending spokes attached thereto, each pair of spokes beingconnected at their inner ends forming a spring-seat, a spiral s ring within each seat,-removable means for olding said spring in place and a connection between hub-spokes, substantially as described. l

2. -A vehicle -Wheel comprising a hub, a series of radiating spokes symmetrically disposedthereon, a rim and a series of inwardlyextending spokes attached thereto, each pair of spokes being connected at their inner ends forming a spring-seat, a spirals rin within each seat, removable means for ol ing said spring in lace and a connection between the 6 5 ,outer en of said hub-spokes and the inner ers are completed by the addition .of 5 detachable segments 11, secured in place by end of said spiral springs, substantially as de- 3.

A vehicle-Wheel comprising a hub, spoke-flanges thereon, a series of radially-disposed s okes secured to said flanges, a rim, a series ol)inWardly-extending spokes attached thereto, each pairoispokes being connected at their inner ends forming spring-seats and overlapping the outer ends of the hub-spokes, a spiral spring within each seat, removable means for holding said spring in place, and a connection between the outer ends of said hub-spokes iand the inner ends of said spiral springs, substantially as described.

5. A vehicle-Wheel comprising a hub, spoke-anges thereon, a' seri es of radially-disposed bifurcated spokes secured .to said flanges, a-rim, a series of inwardly-extending spokes attached thereto, each pair of spokes beingconnected at their inner ends forming spring-seats and overlapping the outer ends of the hub-spokes, a spiral spring within each seat, removable means for holding said spring in place and a rod connecting-the outer end of each of said bifurcated spokes and attached to the inner end of said spiral spring, substantially as described.

6. A vehicle-wheel comprising a hub, a rim having a plurality of seats o spring-retaining cylinders provided with removable sections, and a series of spiral springs located one in each of the said seats and having their centers connected to the hub of the wheel.

7. A vehicle-wheel comprising a hub, a rim having a plurality of U-shaped spokes the inner ends of which are formed into spring seats or recesses, and a series of spiral springs located one in each of said seats and a connection between the center of each of said springs and the hub of the wheel.

8. A vehicle-wheel comprising a hub pro- .vided with two sets of radiating spokes symmetrically disposed about said hub, connecting means or rods located at the outer ends oi each pair of spokes, a series of indupendently-removable spiral springs the inner portions of which are connected to said spokeconnecting rods, a rim and connecting nwans between said rim and the outer portions of said sprinrs 9.
